Hello! Is xfsdump an ancient relic or something recommended to new users (I have never seen anyone recommending it)? I gave it a try and found the incremental backups to be really fast! How are incremental backups implemented? I saw that my inventory file is really small. Does it use some internal xfs metadata to detect changes? Is it resilient against all kinda renames and changing timestamps etc that a user might do? (I've previously used a backup system that broke when doing stuff like that) Is it possible to backup (and restore) ctimes? I read that the incremental backups are limited to a depth of 10. Are they intended to be used in a binary tree like fashion? -- Stevie Trujillo |
